BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cleaning system and, moreparticularly, to a cleaning system for treating water and the removal offloating debris for above-ground swimming pools or other above-groundfluid containers. The present invention further relates to an integratedabove-ground swimming pool pump-filter-skimmer system, and to animproved side wall-mounted housing and replaceable cartridge filter forsuch integral systems.

2. Description of Related Art

Cleaning systems for swimming pools are known in the art. Some existingintegrated swimming pool cleaning systems include a pump, skimmer, andfilter for cleaning the water contained within the pool. Most suchcleaning systems for above-ground pools are supported using a groundlevel base beside the pool wall, due to their heavy weight.

Such designs present a potential safety hazard in use, because cleaningsystems are often misused as a step for pool entry or exit, particularlyby children. In addition to safety risks, use of the cleaning systemhousing for ingress and egress places a significant physical strain onthe mounting and plumbing connections, and can lead to functional leaksor failures. Moreover, existing integrated swimming pool cleaningsystems for above-ground pools are applicable only for use on rigid wallpool designs with straight vertical side walls.

An exemplary conventional cleaning system is shown in FIG. 1A. Aconventional cleaning system 20, which is fully supported by a base 10,is in communication with the above-ground pool 100.

What is needed, therefore, is an improved cleaning system forabove-ground pools, wherein the cleaning system is fully supported bythe pool, and there is no need for a base. It is to such a device thatthe present invention is primarily directed.

Embodiments of the present invention are directed towards devicescombining swimming pool filters, skimmers, and pumps into integral,sidewall-mounted systems for above-ground pools, and methods for the useof such systems to remove both larger floating debris and smallerparticulate matter to maintain water clarity and hygienic safety withinsaid pools.

To facilitate an understanding of the principles and features of theinvention, it is explained hereinafter with reference to itsimplementation in an illustrative embodiment. In particular, theinvention is described in the context of being a cleaning system for anabove-ground swimming pool. Because of its light weight, the cleaningsystem can be solely supported by a side wall of the container.

The invention, however, is not limited to its use as a cleaning systemfor an above-ground swimming pool. Rather, the invention can be used toclean many different above-ground containers capable of holding a fluidthat is needed or desired. Thus, the cleaning system for filtering andskimming the water in a swimming pool described herein after can alsofind utility as a cleaning system for a cleaning a variety of fluidscontained in various above-ground containers.

The material described hereinafter as making up the various elements ofthe container of the invention are intended to be illustrative and notrestrictive. Many suitable materials that would perform the same or asimilar function as the materials described herein are intended to beembraced within the scope of the invention. Such other materials notdescribed herein can include, but are not limited to, materials that aredeveloped after the time of the development of the invention, forexample.

An environment of the present invention is illustrated in FIG. 1B. Anabove-ground pool 100 can solely support a cleaning system 200 forcleaning the water in the pool. Specifically, a base is not needed tosupport the cleaning system 200; rather, a side wall of the pool isadapted to fully support the cleaning system 200.

Above-Ground Swimming Pools

Referring now to the drawings, wherein like reference numerals representlike parts throughout, the cleaning system is securable and supported bya container, or portable swimming pool, constructed in accordance withthe following description. Four different containers can be seen in theperspective views illustrated in FIGS. 2A-2D. As shown in FIGS. 2A-2D,an above-ground swimming pool 100 has a base 110 and a side wall 120,which is made from a physical material and is formed in a particularshape.

The pool 100 can be a frame pool or a pop-up type of pool, both of whichbeing collapsible in nature. First, the frame pool is typicallypre-fabricated and includes a plurality of external vertical braces orframes for supporting the frame pool above the ground (see FIGS. 2A and2B). The frame pool can be made of metal, plastic, and the like. Second,the pop-up pool is adapted to rise with the amount of water insertedinto pool (see FIG. 2C), and can also be outfitted with external bracesor frames for additional support (see FIG. 2D). As one skilled in theart would appreciate, other types of pools can be used with the presentinvention.

The shape of the pool 100 can be circular, oval, and the like. The pool100 can be made in a variety of shapes, including, but not limited to,rectangular, square, oblong, oval-shaped, elliptical, rectangular withrounded corners, and the like. Thus, it will be apparent to one skilledin the art that the configuration of the pool 100 can be many shapes.Different shapes can result in the pool 100 having more than one sidewall 120 forming the perimeter of the pool 100. Additionally, the pool100 can be made in a variety of sizes, depending upon the desired use.

The pool 100 is formed with the base 110 and side wall 120. The base 110and side wall 120 can be manufactured out of many different materialsand can be formed of the same materials or each a different material.For example, the base 110 and side wall 120 of the swimming pool 100 canbe formed from a textile (e.g., burlap, etc.) or synthetic material(e.g., plastics, polyurethane, PVC, nylon, etc). Many materials(especially water-permeable textiles, etc.) can be used to construct apool; the materials, however, should be treated to retain water. Forexample, such materials could be adhered to, laminated with, coatedwith, or bonded to a material impermeable to water. In accordance with apreferred embodiment, the base 110 can be formed from a nylon shell,which can be laminated or otherwise treated to hold water. For example,the nylon shell might be bonded to another material, such aspolyurethane, PVC, vinyl, or other suitable impermeable lining toprovide the desirable waterproof qualities, and to provide a morepleasing tactile quality to the interior of the pool 100. Similarly, thewall 120 of the pool 100 can be constructed from these materials, orother materials having similar suitable qualities. Many of the materialsthat are used can be selected for their durability.

For example, the base 110 can be formed from materials that can be moredurable than the side wall 120, as this section of the pool 100 wouldlikely be subjected to more wear than that experienced by the side wall120. Also, as described, the base 110 and side wall 120 can be formedfrom a combination of materials, which can be adhered or bondedtogether. The materials used for the various portions of the pool 100,including, for example, the base 110 and the side wall 120, can bejoined by way of a number of commonly known suitable techniques, such assewing, adhesives, bonding, lamination, RF welding, other suitablejoining techniques, and the like. The connection of the base 110 to theside wall 120 can be along the bottom 122 of the side wall 120. The base110 includes a perimeter, wherein the side wall 120 can be connectedabout the perimeter of the base 110.

The side wall 120 can include an inner wall 126 and an outer wall 128.The inner wall 126 is sealable to the outer wall 128. The side wall 120is preferably non-inflatable. Further, the side wall 120 is preferablynon-spring activated.

In one embodiment, the inner wall 126 can be made of pliable plastic,while the outer wall 128 is made of hard plastic. Then, inner wall 126can limit leakage of fluid should the outer wall 128 crack. Likewise,the material of the inner wall 126 can be made of hard plastic, and thematerial of the outer wall 128 can be made of pliable material toprotect from potential leakage should the hard plastic crack.

In another embodiment, the inner wall 126 can be made of hard plastic,while the outer wall 128 can also be made of hard plastic.

The pool 100, as illustrated in FIGS. 2C-2D, can further include afloatation device 130, which is formed in the shape of the pool 100,attached to the top 124 of the side wall 120. According to an exemplaryembodiment shown in FIGS. 2C-2D, the floatation device 130 can be aninflatable ring 132. This inflatable ring 132, when inflated, canprovide some stiffness at the top 124 of the side wall 120, and can helpmaintain the overall shape of the pool 100. Moreover, the inflatablering 132 can provide padding for those entering and exiting the pool100, and can also provide a manner by which the pool 100 changes from acollapsed to an expanded configuration with the addition of water withinthe pool 100. Additionally, as the floatation device 130 can be buoyant,it can be made to rise with the level of water within the pool 100, suchthat as water is deposited in the pool 100 and the floatation device 130rises with the level of that water, the side wall 120 is automaticallyerected as the pool 100 is filled.

The floatation device 130 can be made from a variety of materials. Forexample, the floatation device 130 can be a standard inflatablepolyurethane casing, or similar casing that is suitable for retainingair or other gas in an inflated state. Additionally, the floatationdevice 130 can make use of a variety of chemical or other reactions thatwould automatically inflate it. The floatation device 130 can beinflated by conventional means, for example by a valve configured fororal inflation or for inflation by a device such as a pump, and thelike.

The floatation device 130 can also be made from material that does notrequire inflation, but provides adequate buoyancy and floats on thewater contained within the pool 100 (or other fluid when the pool isused as a general container). For example, special foams, polystyrene,or other materials can be used to create a floatation device 130, whichwould float with the water line contained in the pool 100, and cause thewalls 120 to be erected as the pool 100 fills. In this manner, the pool100 can automatically change from a collapsed to an expandedconfiguration. As the pool 100 is a collapsible pool, and adapted to befolded, the floatation device 130 can be made of a material that can besubjected to folding, without becoming damaged. Those skilled in the artwill appreciate that, although some potential materials from which thefloatation device 130 can be formed have been mentioned above, othermaterials including, but not limited to, newly developed materials canbe incorporated within the design of the invention, and used to form thefloatation device 130 without departing from the invention.

It will be appreciated by those skilled in the art that the floatationdevice 130 can be of a nature other than an inflatable ring. Forexample, this floatation device 130 can be made of a material thatfloats, and is bendable, such that it can be folded or bent.

The pool 100 can be conveniently collapsed for storage and/or transportby deflating the inflatable ring 132 and folding onto itself along withthe base 110 and side wall 120 material in a manner that is well known.

Additionally, as illustrated in FIG. 2C, the pool 100 can comprise aporthole 150, or a plurality thereof. The portholes 150 are translucentsections of the side wall 120, either integrally formed in/with the sidewall 120, or separate elements. The portholes 150 are adapted like awindow permitting one to see into the pool 100. Similarly, the portholes150 enable one within the pool to see outside the pool 100. Theportholes 150 can further enable determining the level of fluid withinthe pool 100.

The portholes 150 can be of a particular shape. For instance, the shapeof the portholes 150 can be oval. Alternatively, the shape of theportholes 150 can be round or circular. As will, however, be apparent toone skilled in the art, the configuration of the porthole 150 can bemany shapes. In a preferred embodiment, the locations of the portholes150 can be placed symmetrically about the side wall.

The portholes 150 can aid in safety, as the portholes 150 can enableviewing into the pool 100 through the side wall 120. If the portholes150 are removably designed by suitable means, the porthole 150 can alsobe used as a drainage device, enabling quick emptying of the fluid ofthe pool 100. The portholes 150 can be integrally formed duringmanufacturing of the side wall 120, or removable, wherein they areattached via a waterproof/leak resistant means. The portholes 150 canalso be included via a non-removable method, wherein the portholes aresecured within the side wall 120.

The portholes 150 can be secured in different ways within the side wall120. In one embodiment, the portholes 150 can be flush with the sidewall 120, such as enabling a drainage device. In another embodiment, theportholes 150 can be insertable between the inner wall 126 and the outerwall 128 of the side wall 120. Preferably, the portholes 150 are sealedbetween the inner wall 126 and the outer wall 128, wherein there is ahole between the inner wall 126 and the out wall 128, whereby theporthole seals the hole. The porthole 150, thus, can be sandwichedbetween the inner wall 126 and the outer wall 128. The porthole 150 canbe sealed by conventional compression or heat sealed methods.

FIGS. 2A, 2B and 2D also illustrate the pool 100 having a one or morebraces or structural support members 160. The support member 160 caninclude vertical rib supports, and can be coupled proximate to the sidewall 120 of the pool 100. For example, the support member 160 can beinserted within the material making up the side wall 120. The supportmember 160 can comprise at least a portion of the floatation device 130,and can have at least a portion coupled to the top of the side wall 120and vertically along the side wall 120 to provide buoyancy and/orrigidity to the side wall 120. The support member 160 can comprise, forexample, one or more inflatable bladders, collapsible foam, removablesupport members, or the like.

One skilled in the art would appreciate that the support members 160 canbe used on a frame pool, as well as a pop-up pool for supporting thepool above the ground. In an exemplary embodiment, the support member160 are positioned outside the pool 100.

The pool 100 can include a ladder (not shown) to enable one to enterand/or exit the pool 100. The ladder can be integral with the supportmember 160, or not. The ladder can further be insertable into the pool100, enabling one to exit the pool 100. Because a rim of the pool 100 isabove the ground, the ladder is preferably flush with the rim for easyentry/exit from the pool 100.

Because the pool 100 is collapsible, the fluid in the pool 100 should bedrainable. Preferably, a drainage assembly 180, as illustrated in FIG.2D, is integral with the pool 100. In an exemplary embodiment, thedrainage assembly 180 is a cork or like device, that is removeable fromthe pool 100, such that, when removed the water from the pool 100 can bedrained. The drainage assembly 180 can also be a valve enabling controlof draining the pool 100. One skilled in the art would appreciate thatthe drainage assembly 180 can be many devices enabling easy draining ofthe pool 100, safely and environmentally.

From the foregoing, it can be seen that the above-ground containerprovides a number of different collapsible containers, which can be usedas swimming pool. The various embodiments described above providecollapsible swimming pool that are foldable, enable easy storage, andincrease portability when compared with prior approaches. Additionally,according to various embodiments, the collapsible swimming pool can beprovided with a pop-up mechanism that automatically erects the pool toits full-sized, expanded configuration. The swimming pool can beconstructed from durable, lightweight, foldable materials which are noteasily damaged, and therefore contribute to their long life.

More specifically, the present invention is a cleaning systemfor cleaning, filtering, and skimming the water in an above-groundswimming pool. The cleaning system is lightweight enough such that theside wall of the above-ground swimming pool can support the entiresystem. As a result, a ground level base beside the pool wall is notneeded.

FIG. 3 is a perspective view of the cleaning system 200. The cleaningsystem 200 is capable of removing debris from the above-ground containeror swimming pool 100.

The cleaning system can comprise a housing, a filter assembly, a skimmerassembly, a pump assembly, and a return line. The housing defines ahollow cavity, and is supported by the side wall of the above-groundcontainer. The filter assembly is disposed within the hollow cavity, andis adapted to filter debris in the fluid of the above-ground container.The skimmer assembly is also disposed within the hollow cavity, and isadapted to gather debris off a top surface of fluid contained within theabove-ground container. The pump assembly is removably securable to afirst end of the housing, and is adapted to control the filter assemblyand the skimmer assembly. The pump assembly is further adapted toextract fluid and debris from the above-ground container to be filteredby the filter assembly and be gathered by the skimmer assembly. Thereturn line is coupled to the side wall as well as the pump assembly,and is adapted to permit fluid extracted from the above-ground containerto be inserted into the above-ground container.

The housing is supported to the side wall of the above-ground containerby an attachment assembly. Preferably, the housing is connected to theabove-ground container by gaskets, such that no element penetrates theside wall. The return line is coupled to the side wall via a return linepool connector assembly.

FIG. 3 illustrates the cleaning system 200 comprising housing 205 andthe pump assembly 300. The housing 205 defines a hollow cavity 210 forhousing the filter assembly 400 (see FIG. 4) and skimmer assembly 500(see FIG. 4).

The housing 205 includes a bottom portion 215 and a top portion 220. Thepump assembly 300 is preferably coupled to the bottom portion 215 of thehousing 205. While the exemplary housing that is illustrated the figuresis generally cylindrical, housings in various embodiments of the presentinvention can take many shapes, for example and not limitation,rectangular, rounded, non-rounded, polygonal, and the like.

Referring now to FIG. 4, an exploded view of the cleaning system 200 isillustrated. As mentioned, the cleaning system 200 includes a housing205, a pump assembly 300 coupled to the bottom 215 of the housing 205, afilter assembly 400, and a skimmer assembly 500. FIG. 4 also shows theattachment assembly 600 by which the cleaning system 200 is secured tothe pool 100, and the return line pool connection assembly 700, by whichthe return line 350 is coupled to the side wall 120.

The top portion 220 of the housing 205 can be configured to receive alock top 225, which can be received by threads, locking detents, orother securely engaging retaining means within said housing top portion220, preferably at the top end 220 t. The lock top 225 can be removable,enabling access into the hollow cavity 210.

The filter assembly 400 and skimmer assembly 500 can be disposed in thedefined hollow cavity 210 of the housing 205.

The filter assembly 400 positioned within the housing 205 can include aremovable filter cartridge 405. The filter cartridge 405 can be sizedand provided to filter water-borne particulate matter, for example andnot limitation, debris too small to be first retained by the skimmerassembly 500.

The skimmer assembly 500 is preferably positioned above the filterassembly, and first catches the debris. Specifically, adjacent to thehousing top end 220 t, a skimmer port 505 can be in open fluidcommunication with the interior of the housing 205. A removable strainerbasket 510 is provided to be retained within the housing 205.Preferably, the strainer basket 510 is positioned below water level 170of the pool 100, such that water entering the housing 205 through theskimmer port 505 first drains through the removable strainer basket 510.

The filter assembly 400 and the skimmer assembly 500 are controlled bythe pump assembly 300. Preferably, the pump assembly 300 is positionedat the bottom end 215 b of the housing 205. The bottom end 215 bincludes an aperture 230 which is sized and situated to directly connectwith the pump assembly 300.

The pump assembly 300 includes a pump 305 without the need forintervening pipes or other intervening connections. The pump 305includes a pump inlet 310 and a pump outlet 315, and can be secured tothe housing 205 by a pump retainer 235. As shown in both FIGS. 4 and 7,the retainer 235 can be received into threads, locking detents, or othersecurely engaging retaining means on the inlet 310 of the pump 305. Inaddition, an optional O-ring 320 or other washer or gasket can beinterposed between said pump inlet 310 and the pump retainer 235ensuring a watertight connection therebetween. Similarly, an O-ring 320or other washer or gasket can be interposed between the pump outlet 315and a return hose 350. The pump inlet 310 and the return hose 350 can beconnected by a hose clamp 355 or other connector to ensure a watertightconnection therebetween.

Still referring to FIG. 4, the return hose 350 can extend a desireddistance away from the housing 205 to allow adequate separation betweenthe water intake through the skimmer assembly 500 and a connectionassembly 700, or more specifically a fitting 705 of the connectionassembly 700. The return hose 350 connects to the return pool wallfitting 705 through a series of watertight connections.

For example, as shown in the exemplary embodiment of the presentinvention in FIGS. 3-4 and 9-10, the return hose 350 can connect to anelbow fitting 710 using an interposed O-ring 320 or other washer orgasket and a hose clamp 355 or other connector to ensure a watertightconnection therebetween. The elbow fitting 710 can connect the returnpool wall fitting 705 through a return aperture 715 in the side wall 120of the pool 100. A watertight connection between the elbow fitting 710and the return pool wall fitting 705 can be achieved using a pipe nut720 and a thrust washer 725 on the outer side wall 120 of the pool 100.Furthermore, a gasket 730 between the return pool wall fitting 705 andthe inner side wall 120 of the pool 100. The return pool wall fitting705 can be fitted with a diverter fitting 735 secured by a locking ring740 to divert return water flow away from the skimmer port 505.

Referring back to the skimmer port 505, it can be attached to the sidewall 120 of the pool 100 through the aperture 190 (see FIG. 2C). Theattachment assembly 600 includes an outer skimmer gasket 605 that can bepositioned between the outer surface of the side wall 120 of the pool100 and an inner gasket 610 and a skimmer face plate 615 on the innerside wall 120 of the pool 100. The skimmer port 505 can be attachedflush to the outer skimmer gasket 605. The skimmer face plate 615 canalso be flush to the inner gasket 610, without the need of a flange,lip, or other projection of the skimmer port 605 or skimmer face plate615 extending through the sidewall 120 of the pool 100. The skimmer port505, outer skimmer gasket 605, inner gasket 610, and skimmer face plate615 can be attached through the side wall 120 using a plurality ofsecuring mechanisms 620, such as screws or other fasteners to achieve awatertight connection between the skimmer port 505 and the skimmer faceplate 615.

As shown in FIGS. 4 and 8, in various exemplary embodiments of thepresent invention, the connection of the skimmer port 505 to the skimmerface plate 615 as shown above through the side wall 120 of anabove-ground pool 100 can suffice as the only needed physical support tomount and maintain the entire cleaning system. In some embodiments ofthe present invention and as shown in FIG. 3, the housing 205 canfurther be provided with a stabilizing foot 240 that can rest against orbe attached to the outer surface of the side wall 120. In otherembodiments of the present invention not shown in the figures,additional support connections can be employed between the housing 205and the vertical and/or horizontal frame elements that support the linerof an above-ground pool 100.

The skimmer face plate 615 is shown in FIGS. 4 and 8 to be provided witha weir 625. The weir 625 is pivotally attached to the skimmer face plate615 in such a manner to restrict movement of the weir 625, such thatwater flow can be admitted through the skimmer port 505, but the weir625 is close enough against the skimmer face plate 615 to restrict wateregress through the skimmer port 505. The weir 625 can further beprovided with one or more weir foam elements 630 to assist the weir 625in restricting water flow when the pump assembly 300 is not operating.

In operation, in the exemplary embodiment shown in FIG. 4, the pump 305of the pump assembly 300 can draw water from the pool 100 by the weir625 into the skimmer port 505. Large particulate matter suspended in thewater is collected by the strainer basket 510. The filter cartridge 405can be provided with a space to contain chlorine tablets or otherchemical delivery devices to maintain a desired antimicrobial chemicallevel within the water. Smaller particulate matter within the pool waternot removed by the skimmer basket 510 is then removed by the filtercartridge 405 as the water is drawn through the hollow cavity 210 of thehousing 205 and into the pump inlet 310. Water flow then exits the pump305 through the pump outlet 315, and enters the return hose 350 toreturn to the pool 100 through the pool wall fitting 705.

Access for emptying the strainer basket 510 and replacement of thefilter cartridge 405 is achieved through removal of the lock top 225 bya user, whereupon the strainer basket 510 and the filter cartridge 405can be readily removed from the housing 205 and replaced as desired orneeded.

As shown in FIGS. 4 and 8, if desired, a user can connect a pool vacuumconnector 245 which is sized and configured to fit through the weir 625and skimmer port 505 to sealably fit atop the strainer basket 510 withinhousing 205 below water level 170. Embodiments of such a pool vacuumconnector 245 according to the present invention can be provided with aconnector for a vacuum hose connecting to a vacuum device (not shown).In such embodiments, when the pool vacuum connector 245 is attached,negative water pressure from the pump assembly 300 can be used to powera pool vacuum device to remove debris on the bottom of the pool (e.g.,sitting on the base 110), with debris collected by the strainer basket510 and removable filter cartridge 405.

In use, the pump assembly 300 can be controlled by an electrical timeror other electrical or electronic control means (not shown) to allowintermittent or continuous pump operation as desired by a user.

In essence, the cleaning system is adapted to remove debris via theskimmer assembly and the filter assembly, by pulling water into thehousing via the pump assembly. The cleaning assembly is lightweightenough to be fully supported by the side wall of the pool, such that abase or other mechanism is not needed to properly position the cleaningsystem.

Pump Assembly

FIG. 5 illustrates an exploded view of the pump assembly 300. As noted,the pump assembly 300 is adapted to control the operation of thecleaning system 200. Specifically, the pump assembly 300 can pull fluid,typically water, from the above-ground container, preferably theabove-ground swimming pool, to be skimmed by the skimmer assembly 500,and then filtered by the filter assembly 400.

The pump assembly 300 includes the pump 305, which is the device thatpulls the fluid towards, and ultimately into, the housing 205. The pumpassembly includes a pump body 325 to contain the pump 305. A rotorassembly 800 (shown in more detail in FIG. 6, and described more below)can be coupled to the pump body 325. A pump gasket 330 is positionedatop the top portion 325 t of the pump body. A volute housing 335provides the pump inlet 310 and pump outlet 315 for fluid to enter/exitthe pump assembly 300.

Preferably, the volute housing 335, pump gasket 330 and rotor assembly800 are secured to the top portion 325 t of the pump body 325 withsecuring members 340, such as screws, bolts, and the like.

Rotor Assembly

Referring now to FIG. 6, the rotor assembly 800 of the pump assembly 300is illustrated in a perspective view. The rotor assembly 800 includes anelongated shaft 805 having a first end 807 and a second end 809. Theshaft 805 can be received by the axle 810, and connected the impeller815 via an end cap 820 and washer 825 at the shaft's first end 807. Theaxle 810 is preferably magnetic. At the both ends 807 and 809 of theshaft 805 are positioned with an end cap 820 and washer 825.

The pump assembly 300 is adapted to rotate the rotor assembly.Specifically, the pump 305 rotates the shaft 805, which rotates theimpeller 815. Together with the pump assembly 300, the rotor assembly800 enables water to be pulled into the housing 205 of the cleaningsystem.

Method of Installation

The present invention includes a method of installing the cleaningsystem 200. Preferably, the cleaning system 200 can be secured to theswimming pool 100, and does not need the assistance of a separate baseto be supported.

Due to risk of electrical shock, it is preferred that the cleaningsystem 200 be connected to a grounding type receptacle protected by aground fault circuit interrupter (GFCI). The receptacle is preferably atleast ten feet away from the pool 100.

To install the cleaning system, the lock top 225, strainer basket 510,and filter cartridge 405 can be first be removed from the housing 205.Then, the O-ring 320 for the pump assembly 300 can then be lubricated,preferably with petroleum jelly.

Subsequently, the pump assembly 300 can be connected to the bottomportion 215 of the housing 205. The pump assembly 300 is preferablyconnected, such that the volute housing 335 extends out to a side of thehousing 205, as illustrated in FIG. 7. The pump assembly 300 can beinserted until it bottoms out, and the ribs on the volute housing 335insert into two slots on the bottom of the housing 205. The retainer 235can be then be tightened to the volute housing 335, specifically to thepump inlet 310.

Installation continues by locating the mounting location for thecleaning system 200 on the side wall 120 of the pool 100. The innergasket 610 and the face plate 615 are installed on the inner side wall126 (inside the pool 100) by securing mechanisms, preferably screws andthe like, as shown in FIG. 4. The outer skimmer gasket 605 can besecured to the outer side wall 128 (outside the pool 100), and securedalso by securing mechanisms. The housing 205 can be coupled to the outerskimmer gasket 605.

The connection assembly 700 for the return line can be installed. Thegasket 730 can be lubricated, and then installed over the threads of thereturn pool wall fitting 705. The return pool wall fitting 705 can beinserted through an aperture 715 of the side wall 120. A thrust washer725 can be placed over the return pool wall fitting 705, and then a pipenut 720 can be threaded until the return pool wall fitting 705 is handtight. It is preferable that the return pool wall fitting 705 not beover tightened, as this can cause wrinkles in the side wall, which couldultimately compromise the integrity of the side wall 120. Next, tape,such as Teflon® tape, can be applied to the thread of the elbow fitting710, and it can be installed to the return pool wall fitting 705.

Next, the return hose 350 can be secured to the pump assembly 300 andthe return connection assembly 700. As shown in FIG. 9, the return hose350 has a first end 352 connected to the pump assembly 300, and a secondend 354 connected to the connection assembly 700.

The first end 352 of the return hose 350 is connected to the pumpassembly 300 by a hose clamp 355. The hose clamp 355 can first beloosened before sliding it over the first end of the return hose 350. Itis preferable to lubricate the O-rings 320 on the volute housing 335,and on the elbow fitting 710 before installing the O-ring 320 on thereturn hose 350. Specifically, the first end 352 of the return hose 350can be connected to the volute housing 335 of the pump assembly 300. Thesecond end 354 of the return hose 350 can be connected to the elbowfitting 710 of the connection assembly 700. Both of the hose clamps 355can then be tightened.

The filter assembly 400 and skimmer assembly 500, including the filtercartridge 405 and the strainer basket 510, can be re-inserted back intothe housing 205. The filter cartridge 405 can slip over the retainer235, and preferably seals at the bottom of the housing 205. Accordingly,the strainer basket 510 can then sit in a groove in the hollow cavity210 of the housing 205. The lock top 225 can then be twisted back intoplace until locked.

The weir foam element 630 can be inserted into the weir 625, and underweir tabs to secure the weir foam element 630 in place. The weir 625 canbe slid into grooves inside the pool 100, and once inside can be flippedover to be locked into place. The weir 625 can be pushed in the grooves,as shown by Arrow #1 of FIG. 8. After the pool 100 is filled with water,it is preferable that all hose connections and fittings are checked toensure that there is no leakage.

Method of Cleaning Filter Assembly

The present invention also includes a method of cleaning the filterassembly 400.

Before cleaning the filter assembly 400, power to the cleaning system200 should be turned off. Also, the strainer basket 510 and the filtercartridge 405 can be removed from the housing 205.

The filter cartridge 405 can be cleansed of coarse direct and debris bypressure washing, ensuring that between the pleats of the cartridge arewashed. It has been found that fine particles are more easily removedfrom the pleats when the cartridge 405 is dry. Therefore, it ispreferable that after pressure washing the cartridge 405 it should beallowed to dry and then carefully brushed. The pleats, however, shouldnot be scrubbed. Cleaning or scrubbing the filter cartridge 405,specifically the pleats, too vigorously will wear it much faster thansimply hosing it off.

Suntan oils, body oils, algae, and the like can form a coat of film onthe pleats of the filter cartridge 405, which oftentimes can not bethoroughly removed by pressure washing. Such films of oils and/or algaecan quickly clog the filter's pores, and thus greatly reduce filtration.Therefore, it is preferable to remove such materials from the filtercartridge as soon as possible.

To remove oils, it is preferable to soak the cartridge in a solution ofone pound of tri-sodium phosphate (or other strong detergent) to fivegallons of water for up to twelve hours. Tri-sodium phosphate is acommonly available detergent solution. After the oils have been removed,it is preferable to rinse the cartridge to remove remaining dirt.

If, however, algae are a problem, it is preferable to add half a pint ofpool chlorine or one pint of liquid household bleach to the abovecleaning solutions one hour before removing the filter cartridge fromthe solution. Then, thoroughly rinsing the filter cartridge isrecommended before replacing the cartridge.

Method of Diverter Fitting Use

The present invention further provides a method of the using of adiverter fitting in the pool. Using a diverter fitting 735 can divertthe direction of return water entering the pool 100. The diverterfitting 735 can be adjusted by loosening the locking ring 740. Then, thediverter fitting 735 can be used to generate clockwise rotation of poolwater toward the skimmer assembly 500.

To do so, slightly tighten the locking ring 740 and rotate the diverterfitting 735 upwardly to cause water horizontally under the water surfaceto point away from the housing 205, or more specifically the skimmerintake area. It is preferable that the diverter fitting 735 not bepointed directly toward the skimmer intake area, as this will decreasethe skimming and filtration, because water is not being forced about thepool 100. The locking ring 740 can then be tightened once the desiredposition of the diverter fitting 735 is determined. The diverter fitting735 can be positioned downwardly—towards the base 110 of the pool 100—toassist in keeping settlement from building along the bottom of the pool100.

Method of Vacuum Adapter Use

The present invention also provides a method of using a vacuum adapterwith the cleaning system 200. The cleaning system 200 is adapted toreceive a vacuum adapter or pool vacuum connector 245, enablingvacuuming of the bottom surface, or base 110, and/or the side wall 120of the pool 100.

The pool vacuum connector 245 is adapted to be coupled to a pool vacuum(not shown), which can be in communication with a pool handle (notshown), as well as a vacuum hose (not shown).

To install the pool vacuum connector 245, the pump assembly 300 shouldbe initially turned off. The weir 625 can be removed.

The pool vacuum can be connected to its handle, and the lowered into thepool 100. The vacuum hose, which may float, is connected to the poolvacuum at a first end, and the second end, which is loose, can bepositioned near the diverter fitting 735. The pump assembly 300 can beturned on, and then by placing the second end of the vacuum hose up tothe diverter fitting 735 enables water to fill the hose, which willcause the hose to sink.

Now that the vacuum hose is filled, the pump assembly 300 can again beturned off, and the pool vacuum connector 245 can be slid into theskimmer opening, and the vacuum hose can be connected to the pool vacuumconnector 245.

By restarting the pump assembly 300, the pool vacuum will begin to pulldebris and other particulates through the vacuum. The user can nowvacuum along the desired section of the pool An environment of thepresent invention is illustrated in FIG. 1B. An above-ground pool 100can solely support a cleaning system 200 for cleaning the water in thepool 100.

The vacuum hose should not be used alone, that is without the poolvacuum, as liner damage, to the bottom of the pool, can occur. Also, itis preferred that one not vacuum with the strainer basket 510 or withthe filter cartridge 405 removed, as pump blockage and/or damage canoccur. Further, it is preferred that the vacuum hose not be left hangingout of the pool, as a siphon can occur draining the pool.

When vacuuming is complete, the pump assembly 300, should again beturned off. The pool vacuum connector 245 can be slid out of the hollowcavity 210 and the weir 625 can be reinstalled. The vacuum hose and poolvacuum can then be drained.

Due to the amount of debris gathered, it is recommended that thestrainer basket 510 and filter cartridge 405 be removed and cleaned.
